As

5 soon as the last coil of Wire istaken from said reel, the wire automaticallyshifts to arm 19 of reel 14, and the machine attendant then places more wire on reel 13. It is intended to carry enough wire on each reel to supply the nail machine long enough so that suflicient timeis always available for the machine attendant to placemore wire on one reel, while the -wire on the other reel is being supplied to the nail machine, thus securing continuous operation of thenail machin insofar as theV wire supply is concerned.

Conveyor The conveyor 20 consistsof anfendless belt 21 Y passing around roller 22 at its upper en d and roller 23 at its lower end. Roller 22 is carried on shaft 24 supported in bearings 25 and 26 secured to frame members 1 and 7 respectively, by means of bolts 27 and 28 as shown in Figure 6, the lower end of said conveyor being carried on shaft 29 journaled in bearings30 supported on brackets-31 secured to the oor by means of bolts 32. Said belt conveyor 20 is divided into sections 33 by means of angle flights 34'attached to conveyor belt 21 by means of rivets 36. Extending beneath and along thesides of belt 21 and nights 34, on the nail carrying side of said conveyor, is the guide 37 extendingpartially .around roller 22 in order to guide the flow of the nails 38 into pan 39. At one end of shaft 24, and keyed thereto, is driving pulley 40 driven by means ofbelt 41 from a main line shaft not shown.

The nails passing through the chute of nail machine 8, drop on the conveyor 20 which carries said nails forward, the nights 34 preventing i' ,L the nails from sliding back towards the nail machine. When the nails are carried to a point just beyond the top of the roller 22 they are discharged by gravity into the pan 39, best seen in Figure 2.

Nail receiving receptacle and co-acfzng mechanism Pan 39 is supported by cylindrical lugs 42 and 43, the latter being set in open slots'formed vin levers 44 and 45, which are rigidly, but adjustl ably attached to shaft 47, in bearings 48 secured to frame member 1 byA bolts 49. Attached also to shaft 47 is lever arm 50 having secured thereto, by means of bolts 51,'nger 52. Secured to lever arm 50 is counterweight 53 adapted to bemoved to any desired position along lever arm 50 by means of adjusting and holding screws 54. Nail receiving receptacle, or pan, 39 is so arranged that as the nails fall into said pan from conveyor 20 they may be inspected at any time by the machine attendant, who then tilts said pan, by means of L, shown in Figure 2, until such time as the weight of nails' in said pan overcomes the .weight of the counterbalan'ce 53. In the latterevent pan l39 drops to the position shown in solid lines in Figure 3 and in dropping to this position causes lever arms 44 and 45 to move downwardly thus causing shaftV 47 to revolve which, in turn, raises lever 50 to the position shown in Figure 3. As lever arm 50 raises, 'linger 52 also raises, engaging lug 58 secured to shaft 59, causing. said shaft tomake a partial rotation. Shaft 59- is supportedat one end in bearing secured to frame 1 by means of bolts 61, and at its opposite end by bearing 62 formed in frame support 11. Adjustably secured to nail machine end of shaft 59, is one end of arm 63, the other end of said arm having attached thereto tension spring 64,' the latter being anchored'l at its opposite end by bolt 64 secured in support 11. Secured also to shaft 59 and adapted to move therewith is crank 66, connected to link 68' at bearing 69. Connected also to link 68 at its opposite end at bearing 70 is belt shifting lever 71 set in guide 72, attached to supporting member 12. Secured also to support l2 and guide 72 is -lever 73 having attached theretohandle 74, said lever 73 being adjustably attached to arm 75 by means of link 76, and said arm 75 being attached to belt shifting lever 71 by means of bolt 77.

Consequently, when pan 39 is caused to drop by the weight of nails therein, as has been described, and causes shaft 59 to partially rotate, said rotation causes the belt shifting mechanism to function and stop said nail machine.

With pan 39 in its receiving position as shown in Figure 2 the belt shifting kmechanism of said nail machine, has its various elements arranged as shown in Figure 9. As the shaft ,59 turns, arm 63 moves to a position preventing a return movement of shaft 59, and is held in this position by spring 64 until released by the machine attendant as will be described. The vturning of shaft 59 also moves crank 66, link 68 and belt shifting lever 71 to the position shown in-Figure 10, thus causing belt 78 to shift to the idlerpulley of the nail machine 8 and stop saidmachine.

At the same time that-these operations take place, the `movement of belt shifterY 71 causes lever 75 to move forward which, acting through link 76, causes arm 73 to moveinto an inoperative position. InV the meantime spring 64 holds lever 63 and shaft 59 in a nonfoperative position, thus making it impossibleY to start the nail machine from the pan end of the apparatus.

Consequently, it is necessary for the attendant to remove the nails from pan 39, this causing counterbalance 53 through shaft 47 to move arms 44 and 45 and pan 39 into its original receiving position, and also moves nger 52 out of contact with lug 58. The attendant then shifts belt 78 to the nail machine operating pulley through movementof lever 73 by means of handle 74 thus moving shifting arm 71, link 68, crankl 66 and lever 63 into the position shown in Figure 9, whereuponthe machine again begins operation.

As shown in the drawings Figure 1, wire Wis removed in asubstantiallyyertical direction over pulley 15 and then passed downwardly under pulley 17 and into thefnailmachine 8. The nails discharged from the nailmachine, instead of passing directly into a pan, or box, drop on conveyor 20 by which they are carried to pan 39 as partially shown in Figure 2. When the attendant inspects 'the nails at' proper intervals he tilts pan 39 to the position shown by the dottedlines in Figure 3, thus discharging the nails into buggy 57, without interfering with the machine operation. t

i If, however, the attendant does not inspect the nails before a pre-determined weight of nails accumulates in pan 39, this weight being regulated by the setting of the counterweight 53, then the excess'weight of the nails causes pan' 39 to drop, which, in turn, depresses levers 44 and 45, and the latter workingY through shaft 47 raises lever farm 50 thus causing finger 52 to engage lug 58 of shaft 59. Attached to the ope posite end of said shaft 59 is crank 66 which, Working through link 68 and belt shifter arm '71, causes belt '78 to shift to the idling pulley of the nail machine, (shown in dotted linesin Figure 10) and so shuts the machine down.

In order to again start the machine, it is necessary for the attendant to discharge the nails from pan 39 into buggy 5'7, raise the pan 39 and operating mechanisms to the `position shown in Figure 2, and then by means of handle '74A to move lever and cause belt shifter '71, link 68 and crank 66 to move back into their respective operating positions.

What I claim is:

1. In combination, a nail machine, an endless conveyor traveling inside of guides on its conveying side, and having flights adapted to form conveying pockets associated therewith, said conveying means being adapted to continuously receive products from said nail machine at one of its ends, and discharge said products at its opposite end into a holding receptacle positioned by a counter-balanced support, the latter adapted to move into another position when overbalanced causing an arm associated'therewith tov impart rotative movement to va shaft, causing movement of lever mechanisms adapted to move the driving belt of said nail machinelfrom an operating position to an idling position, thus causing said machine to stop until again engaged by re-shifting said belt, substantially as described.

2. In a nail machine or the like, in combination, means for continuously supplying Wire to said machine, means for continuously conducting the nished product from said machine, container means for receiving said products from said conducting vmeans and holding said products until manually emptied therefrom, and means associated with said holding means ,for stopping the operation of said machine when a predetermined amount of said products has been received by said holding means.
